HEEL-ATTACHING MEANS.

Specification of Letters Patent.

Patented June 15, 1920.

Application filed February 28, 1918. Serial No. 219,596.

To all whom it may concern:

Be it known that I, J OHN ARNOLD Mrron- ELL, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Heel Attaching Means, of which the following is a specification.

In the construction of boots and shoes it is customary to make the heels up as separate structures and then fasten them on to the sole of the shoe, and my invention is directed particularly to means for attaching the heels to the sole part of the shoe.

The methods heretofore employed for this purpose have not always succeeded in holding the heels in place; that is to say, after a short time the heels become loosened and are knocked ofl.

It is the object of my invention to provide a simple, cheap and inexpensive means for securely locking the heels in position on the sole after they have been once forced into place thereon.

Other and further objects of my invention will be apparent to one skilled in the art after a study of the specification and drawings, wherein Figure 1 illustrates a view of a shoe showing one form of sole plate attached tothe heel part thereof.

Fig. 2 is a view of the heel with the facing turned away to show the heel plate used for fastening the heel to the shoe of Fig. 1.

Fig. 3 is an enlarged view showing the heel plate of Fig. 2.

Referring now particularly to the details, wherein like numbers refer to corresponding 1 illustrates a shoe having a sole 2, to the heel part of which'is the line 6-6 on the line 10-10 of 'tened, securely to the to be applied to the shoe.

attached a plate 3. As shown in Figs. 5 and 6, the plate 3 has a portion punched outward forming a bridge 1, there being an opening 5 extending under the bridge 4 and its side walls. Forward of the bridge 4 toward the ,instep part of the heel plate there is a hook 6 thrown upward. As shown in Figs. 9 and 10 the hook 6 is near the beginning of the shank 7, which will be referred to later. As a means for fastening the heel plate 3 to the heel part of the sole 2, I have shown a series of holes 8 by means of which the heel plate 3 may be sewed, or otherwise fassole 2 or heel part of the shoe. i

' It is customary practice in many types of shoes to make the heels out of wood and by way of illustration I have shown my heel plate fastened to a heel of this sort. As illustrated in Figs. 8 and a the heel plate 9 has two lips 10 and 11 formed at its end. These lips are adapted to be bent over the body 12 of the heel and fastened thereto by any suitable means such as screws 13. Adjacent where the lip 10 is bent over the heel, a slot leis punched out. Rearwardly of this slot a ortion of the metal is punched upward forming a hook. In my preferred form, as shown, I have indicated a hook 15 of the bifurcated type having limbs 16 and 17 which have notches 18 and 19 punched therein thereby forming hooks. The limbs 16 and 17 of the hook 15 are so constructed and formed as to have considerable sprin tension, the purpose of which will be clear y apparent on studying the application of the heel to the shoe. fter the heel plate 9 has been fastened to the body of the heel 12 it is customary, where the of wood, to apply a leather facing 20 around the body 12 after which the heel is then ready It will be noted that it is preferable to make the plate 3 so that its contour is somewhat convex and to make the plate 9 so that its contour is concave to lit the convex surface of the plate 3.

In the application of the heel to the shoe the slot 1 1 is caused to engage with the hook 6 which together act as guides for the heel and the limbs 16 and 17 of the hook 15 are forced under the bridge 4, the said limbs being sprung back by engagement with the side walls of the bridge 4. \Vhen the heel is forced all the way home the notches 18 and 19 snap over the side walls 21 and 22 of the body part 12 is made bridge 4 thereby locking the heel permitv nently and securely in position on the heel plate 3.

In the form of sole plate shown in Figs. 7 to 10 inclusive, I have preferred to make the sole plate 3 with a shank 7 which extendsforward toward and through the instep of the shoe thereby adding strength but at the same time giving elasticity to the instep, as it is to be understood that I prefer to make the sole plate 3 out of metal having considerable resiliency.

While I have shown and-tdescribed the bridge 4 of the sole plate 3 and the hook 15 of the heel plate 9 as well as the hook 6 of the sole plate 3 as being punched integrally with their corresponding parts, it will be understood that these parts may be made of separate pieces and riveted, or otherwise fastened, to their respective plates; hence it is to be understood that various changes may be made in the details relating to my invention without departing from the spirit of the same and the scope of the appended claims.

Having thus described my invention what I claim is 1. In a shoe, the combination of, a sole having a plate fastened to the heel part thereof; said plate having a part intermediate its ends projecting outwardly form ing a bridge, and having a hook formed thereon toward the shoe instep; and a heel having a plate fastened to the top portion thereof; said plate having a part intermediate its ends projecting outward forming a hook and having a slot at the instep end, said hook on the sole plate being constructed and arranged to engage'the said slot on the heel plate, and the hook on the heel plate the walls of said bridge, whereby when said heel is forced into position on the shoe sole it is securely locked in working position.

2. In a shoe,-the combination-of, a sole having a plate fastened to the heel part thereof; said plate having a bridge formed thereon and a hook toward the shoe instep, and a heel having a plate fastened over the top portion thereof; said plate having a slot at the instep end constructed and arranged to engage said hook on the sole plate and a bifurcated hook constructed and arranged to engage the walls of said bridge whereby said heel is irremovably held in position on the shoe.

3. In combination a plate having, a portion extending outwardly from its surface forming a bridge, a hook forward of the bridge and a series of holes in the plate for fastening the same to a shoe sole; a second plate having lips at both ends adapted to be bent over and fastened to a heel, a slot at the instep end constructed and arranged to receive said hook and a bifurcated hook said heel is forced into fastened to the topportion thereo extending above the surface of the plate and having its limbs tensioned' so as to snap over the side walls of said bridge when place on the sole plate, as described.

4. In combination a punched plate having, a portion thrown outwardly to form a bridge and constituting part of a locking device and a portion bent up to form a hookwith a series of holes along its edge for sewing the plate to a shoe sole; a second punched plate having, a contour to fit the first plate with lips formed at both endsconstructed and arranged to be bent over and fastened to a heel, a guide slot in said plate near the forward part of the heel, and a bifurcated hook thrown outwardly from the surface of said second plate and having its limbs extending toward said slot and constituting the other part of said locking device whereby when said heel is forced into position on the shoe sole the bifurcated hook and bridge engage to lock the heel securely in position.

5. In a shoe, the combination of, a sole having a plate attached to the heel part thereof and having a shank adapted to be embedded in the sole and extending under.

the shoe instep toward the ball portion thereof; said plate having a hook near the beginning of the shank and a bridge'to the rear of said hook; and a heel having a plate a slot in said plate to engage said hook on the sole plate and a hook for permanently locking around thewal'ls of said bridge when the heel is forced into position on the sole plate.

6.'In a shoe, the combination of a sole having a heel plate with a shank extending forward of the heel for strengthening the sole, said plate having a hook and a bridge member forward thereon with means for fastening to the sole; and aheel having a plate attached thereto with a slot formed therein to engage the hook on the sole plate and a bifurcated hook formed and tensioned to securely engage said bridge member when said heelis forced in position on the sole.

7. A shoe having iifcombination a solev plate with means for fastening it to the sole and having a shank for strengthening the sole, a guide hook and bridge formed on said-plate; and a heel having a late attached thereto, a guide slot aneLhoo formed thereon and adapted to engage respectively said hook and bridge on the sole plate; said bridge and hook constituting a lock to fasten the heel permanently on the shoe.

8. A shoe having in combination a sole plate with means for fastening it to the sole, a guide hook and bridge formed on said plate; and a heel having a plate at tached thereto, a guide slot and a bifurcated hookformed thereon and adapted to engage the hook and bridge on the sole plate, said bridge and bifurcated hook constituting a look to fasten said heel securely to the sole plate.

9. In combination, a plate shaped for attachment to the heel seat of a shoe, a heel having a plate attached thereto and conformin to the contour and contacting with the snrtace of the heel seat plate and unitary means on each of said plates coaeting to guide the heel plate into position on and automatically look it to the heel seat plate, the arrangement being such that the locking means cannot be unlocked when in position on the shoe.

' In witness whereof I aflix my signature.
